Study of the interaction of Zinc sulfide with Europium (III) fluoride by spectroscopic methods

Фізика і хімія твердого тіла
A study was conducted on the interaction of Zinc sulfide, obtained by the method of self-propagating high-temperature synthesis, and purified from oxygen with Europium (III) fluoride. The optical properties of the obtained systems were studied.

Efficient lysis of rhabdomyosarcoma cells by cytokine-induced killer cells : implications for adoptive immunotherapy after allogeneic stem cell transplantation [PDF]

, 2010
Background: Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood and has a poor prognosis. Here we assessed the capability of ex vivo expanded cytokine-induced killer cells to lyse both alveolar and embryonic rhabdomyosarcoma cell lines ...

Lanthanide‐Doped NaGdF4 Nanoparticles as Versatile Luminescent Labels for Cathodoluminescence Mapping

physica status solidi (b), EarlyView.
This study presents a synthesis method for lanthanide‐doped NaGdF4 particles in an aqueous environment. Clearly distinct cathodoluminescence (CL) spectra were observed for europium‐ and thulium‐doped nanoparticles, stable for up to 100 s of excitation time.

Experimental absorption corrections for highly absorbing europium compounds in powder neutron diffraction

Journal of Applied Crystallography, EarlyView.
An experimental method for absorption correction of powder samples containing highly neutron absorbing elements is reported.For materials with strong neutron absorption, such as europium (Eu), the absorption correction method is important but difficult to manage. This is because Eu has a strong isotope dependence. The energy dependence of absorption is

Modelling the observed properties of carbon-enhanced metal-poor stars using binary population synthesis [PDF]

, 2015
The stellar population in the Galactic halo is characterised by a large fraction of CEMP stars. Most CEMP stars are enriched in $s$-elements (CEMP-$s$ stars), and some of these are also enriched in $r$-elements (CEMP-$s/r$ stars).

A Plant‐Based Platform for the Production of Bark Beetle Pheromones

Plant Biotechnology Journal, EarlyView.
ABSTRACT Bark beetle species of the genera Ips and Dendroctonus represent a threat to forests in both North America and Europe. Under normal circumstances, these beetles recycle dying trees into nutrients, but under certain conditions, growing populations can overcome healthy tree defenses and cause severe economic loss in forestry.

Multi‐Elemental Analysis for Geographical Tracing of Chickpeas Produced in Nearby Locations Around a Protected Geographical Indication

Plant, Cell &Environment, EarlyView.
ABSTRACT The multi‐elemental profile has repeatedly been proposed as a reliable indicator of the geographical origin of plant‐derived foods, as mineral composition accurately reflects the local soil geochemistry and environmental factors. However, this approach may fail in distinguishing specimens from nearby locations, which are expected to be exposed

The first-order magnetoelastic transition in Eu2In: A 151Eu Mössbauer study

AIP Advances, 2019
Our 151Eu Mössbauer investigation of Eu2In and Eu2Sn shows that the europium in both materials is fully divalent. We confirm the distinct thermodynamic orders of the magnetic transitions and reveal a remarkable difference between the magnetic ...

Luminescence in sulfides : a rich history and a bright future [PDF]

, 2010
Sulfide-based luminescent materials have attracted a lot of attention for a wide range of photo-, cathodo- and electroluminescent applications. Upon doping with Ce3+ and Eu2+, the luminescence can be varied over the entire visible region by appropriately
